Review on Electric Grinder Cover Case - Autotoolhome Rotary Tool Shield Attachment for Metal Polishing and Cutting Wheel Protection by Larry Blanco

I've compared it to the version of the Dremel A550 eyeguard that came with the accessory for my Dremel 8220 tool and it's almost identical except that the clear plastic protection is not Dremel's name. Even fits in a bag designed to protect the Dremel. Also fits the old Dremel 395 but due to the large diameter of the eyecup there is a step between the front of the tool and the eyecup when installed. The black threaded part on the guard is larger in diameter than the nose of the original 395. It actually fits my Black & Decker RTX rotary tool better than the old Dremel rotary tools. The accompanying documentation says it fits JIE GONG rotary tools, but then lists the tool numbers, which essentially match the Dremel rotary tool model numbers. The model number of the JIE GONG guard is also the same as that of the Dremel guard according to the documentation that came with it. IMO you can't get cloned anymore. The main benefit is that it costs 40% less than a Dremel part.
